Exercise 30

Compute the value of the capacitance necessary to change the power factor in Learning Assessment E9.16 to 0.95 lagging.
Learning Assessment E9.16
An industrial load requires 40 kW at 0.84 pf lagging. The load voltage is 220 0° V rms at 60 Hz. The transmission-line impedance is 0.1 + j 0.25 . Determine the real and reactive power losses in the line and the real and reactive power required at the input to the transmission line.
